i want implementation y(k)=a1 y(k-1)+ b1*u, and u is initiate value.
how learn a1 and b1. is it possible ?
No products are associated with this question.
The documentation in
lists the methods of regression and classification for which this function is applicable. Neural Networks are not mentioned in the list.
However, this does not mean that you cannot form an ensemble by combining the outputs from a number of NNs.
In my experience, simple linear combinations of multiple designs have been very successful. The success results from the "strong learner" capability of NNs.
The differences between designs tend (but are not limited) to be
1. Design (Train + Validation) data subsets
2. Number of hidden nodes
3. Type of hidden node activations (e.g., sigmoidal and Gaussian)
4. Random initial weights
In addition, the function stagewisefit can be used to identify nets whose removable will not significantly decrease performance.
Hope this helps.
i want to just know is it possible work with neural network and Ensemble ? does Ensmeble such az MEthod of Neural ? and how work with neural and Ensemble?
example of matlab we have::
X = [Horsepower Weight];
ens = fitensemble(X,MPG,'LSBoost',100,'Tree');
mileage = ens.predict([150 2750])
mileage = 22.6735
many tnx . i think ensemble is not Leaner just decide. at first i train system with Recurent or dynomic network such as narxnet then out put pass to Ensmeble and Ensmeble Vote best answer. is it true ?
i Read apeper "A new boosting algorithm for improved time-series forecasting with recurrent neural networks" that Work such this. tnxx
